For vmwareDomObjFromDomainLocked and vmwareDomainLookupByID
let's return a locked and referenced @vm object so that callers
can then use the common and more consistent virDomainObjEndAPI
in order to handle cleanup rather than needing to know that the
returned object is locked and calling virObjectUnlock.
The LookupByName already returns the ref counted and locked object,
so this will make things more consistent.
For vmwareDomainUndefineFlags and vmwareDomainShutdownFlags since
virDomainObjListRemove will return an unlocked object, we need to
relock before making the EndAPI call.

The generated source files for dispatching libvirtd RPC messages contain
translations and are thus listed in POTFILES. This means they are
required in order to build libvirt.pot. Rather than changing the files
that go into libvirt.pot dynamically, just unconditionally build the
remote driver sources so they are always available for building
libvirt.pot. This ensures we don't silently loose translation messages
based on configure args.
This fixes the mingw build which needs to create libvirt.pot but has
libvirtd disabled.

Commit id '43f2ccdc' called virDomainDiskSourceDefFormatInternal

The current private XML parsing code relies on the assumption
that NUMA node IDs start from 0 and are densely allocated,
neither of which is necessarily the case.
Change it so that the bitmap size is dynamically calculated by
looking at NUMA node IDs instead, which ensures all nodes will
be able to fit and thus the bitmap will be parsed successfully.
Update one of the test cases so that it would fail with the
previous approach, but passes with the new one.

The problem is in full CPU calculation in virQEMUCapsInitHostCPUModel.
It is supposed to include features emulated by qemu and missed on host. Some of
such features may be not included however.
For Core i5 650 host CPU is detected as Westmere and reported CPU as
SandyBridge. x2apic is missed on host and provided by installed qemu. The
feature is not mentioned in reported CPU features explicitly because SandyBridge
model include it. As a result full CPU does not include x2apic too.
